`IMPROVEMENT IN HORSE-RAKES.

Specification forming part of Letters Patent No. 35,502, dated June 10, 1862.

To all whom it may concern: Y

Be it known that 1, NICHOLAS T. BROWN, of Ononwa, in the county ot' Louisa and State of Iowa, have invented a new and Improved Rake; and I do-hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompa-l nying drawings, making a part of this specification, in whichi Figure 1 is a side sectional view of my iii-- vention, taken in .the line .r x, Fig. 2 5 Fig. 2, a plan or top view of the same.

Similar lettersof'reference indicate corre- -s'ponding parts in the two iigures.

This invention relates to an improved rake of that class which are drawn by a horse or team,

j and are commonly termed horse-rakes.

of removable bearings or caps b b, which are attached to the frame by means of pins c c and keys d, as shown clearly in Fig. 1. By removing the keys d the bearings or ycaps b b may be detached from the frame Aand the rake 'i readily removed and, with the frame, placed on a wagon for conveyance from place toV place. The rake-head a has teeth e passing Atransversely through it, the teeth projecting at equal distances from both sides of the rakehead. The teeth may be of cylindrical form,

and of any suitable length, as may be required.V

B B are two bars, which pass through the rake-head a transversely and at right angles to the teeth e. The bars B' B' are within the frame A, as shown clearly in Fig. 2, and they project at equaldistances from two opposite sides of the rake-head a.

D is a slide, which is formed of a bar placed transversely in the frame A, the ends of the bar being iitted in recesses ff, in the inner sides ot' the side pieces, g g,'of the frame A, the tops ot' the recesses being covered by `caps hh. The ends ot' the slide D are allowed to work freely in the side pieces, g g, of the frame A, and *to the slide the ends of aforked or V- shaped connecting-rod, E, are attached, the front end of which is secured by an adjustable bolt, F, to an upright lever, G, having its fulcrumfpin i in the bar B of frame A. The upper end of thelever G is slotted vertically, as shown atf, Fig. 2, and the inner sides ofthe slot are cut or made of double-beveled form, as shown in said igure, in order to admit of a lever, H, which is fitted in said slot, being moved or adjusted laterally,either to theright or left. The lever H is secured to the slot) of G by means of a fulcrum-pin, 7c, and said lever H may be y adjusted forward, so as to extend in front of the frame A and bar B, or be turned over backward, so as to project over and back ot' the rake, as shown by dotted lines in Fig. 1.

The machine is arranged for use by attaching the bar B of the frame A- to the runningy gear 0f a Wheel-vehicle, as indicated in Fig. l,

the back, part of the vehicle beingf shown in red. If the attendant desiresto ride in the vehicle', the lever H is adjusted forward, sol

that it will extend over the vehicle within convenient reach of the rider or driver. At the commencement of 'the operation the rider or driver shoves back the lever H, and thereby shoves back the slide D, in consequence ofthe 'j latter being connected to the lever G by the rod E, and this slide, when adjusted backward to its fullest extent, is within the path ot' the movement of the bars B B', the front ends ot' which rest or bear on the slide-D and prevent the rake C from revolving under the draft movement of the machine. As the machine is drawn along the rake C performs its work,

and gathers up its load, the lower ends ofthe teeth being in contact with the surface of the ground, and the teeth having a slightlyin eliued position, their lever ends being the farthest forward, as shown clearly in Fig. 1., When the rake has gathered its load the rider or driver draws forward the lever H, and consequently the slide D, and the latter, by this movement, liberates the bars B' B', and the rake G,by means of the draft movement, makes a half-revolution, thereby discharging its load, the driver or attendant shoving back the lever H before the completion of the half-revolution of the rake, so that the bars B B may bearrested and retained by the slide D at the termination of the half-revolution of the rake and the latter again allowed to perform its work.

In case the driver or attendant prefers to Wall; While the machine is in operation, he i pitch or inclination at which the rake-teeth places himself behind the machine, the lever H being adjusted in a backward posit-ion, so as to extend back ot' the rake and rest on the rake-head a. The lateral adjustment of the lever H, which is admitted in consequence of the beveled inner slides of the slot j, enables the driver or attendant to move said lever to the right or left, to suit his position behind the rake. v

The slide D and bars B B form a very simple and eflicient device for stopping and liberating the rake G, and the levers H G and rod E also form a simple mechanism for operating the slide D, at the same time possessing the advantage ofthe slide D being operated either behind or in front of the rake U, so that the driver or attendant may either walk or ride, as he may prefer. 'l`he adjustable bolt E admits ofthe position of the slide D being arranged relatively with the bars B' B so as to insure the latter, when the slide is shoved backward, heilig caught and retained by the slide. The

| stand when at Work is determined by thelength l given to the .bars B B. The shorter these bars are made the greater will be the pitch of the teeth. By regulating the length of these bars B B, I am thus enabled to vary the pitch of the rake-teeth. I am also enabled to dispense with curved rake-teeth, as l can give any desired pitch to the straight rake-teeth in the manner I have described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination ofthe bars B B With the straight rake-teeth e, rake-head a, slide D, rod

E, slotted'lever Gr. and reversible lever H, all

in the manner and for the purpose herein shown and described.
